Optional Method for Outpatient Services: Cost-Based Facility
Services Plus 115 percent Fee Schedule Payment for Professional
Services
(Rev. 3019, Issued: 08-07-14, Effective: 01-01-12, ICD-10: Upon Implementation of ICD- 10, Implementation: 09-08-14, ICD-10: Upon Implementation of ICD- 10)
The BIPA legislation on payment for professional services at 115 percent of what would
otherwise be paid under the fee schedule is effective for services furnished on or after
July 1, 2001. A CAH may elect to be paid for outpatient services in any cost reporting
period under this method by filing a written election with the A/B MAC (A) on an annual
basis at least 30 days before start of the Cost Reporting period to which the election
applies. An election of this payment method, once made for a cost reporting period,
remains in effect for all of that period for the CAH.
Effective for cost reporting periods beginning on or after October 1, 2010 if a CAH
elected the optional method for its most recent cost reporting period beginning before
October 1, 2010 or chooses to elect the optional method on or after October 1, 2010, that
election remains in place until it is terminated, an annual election is no longer required.
If a CAH elects the optional method on or after October 1, 2010, it must submit its
request in writing to its A/B MAC (A) at least 30 days before the start of the first cost
reporting period for which the election is effective. That election will not terminate
unless the CAH submits a termination request to its A/B MAC (A) at least 30 days before
the start of its next cost reporting period.
The Medicare Prescription Drugs, Improvement, and Modernization Act (MMA) of
2003, changed the requirement that each practitioner rendering a service at a CAH that
has elected the optional method, reassign their billing rights to that CAH. This provision
allows each practitioner to choose whether to reassign billing rights to the CAH or file
claims for professional services through their A/B MAC (B). The reassignment will
remain in effect for that entire cost reporting period.
The individual practitioner must certify, using the Form CMS-855R, if he/she wishes to
reassign their billing rights. The CAH must then forward a copy of Form CMS-855R to
the A/B MAC (A), and the A/B MACs (B) must have the practitioner sign an attestation
that clearly states that the practitioner will not bill the A/B MAC (A) or A/B MAC (B)
for any services rendered at the CAH once the reassignment has been given to the CAH.
This “attestation” will remain at the CAH.
For CAHs that elected the optional method before November 1, 2003, the provision is
effective beginning on or after July 1, 2001. For CAHs electing the optional method on
or after November 1, 2003, the provision is effective for cost reporting periods beginning
on or after July 1, 2004. Under this election, a CAH will receive payment from their A/B
MAC (A) for professional services furnished in that CAH’s outpatient department.
Professional services are those furnished by all licensed professionals who otherwise
would be entitled to bill the A/B MAC (B) under Part B.
Payment to the CAH for each outpatient visit (reassigned billing) will be the sum of the
following:
• For facility services, not including physician or other practitioner services, payment
will be based on 101 percent of the reasonable costs of the services. List the facility
service(s) rendered to outpatients using the appropriate revenue code. The A/B
MAC will pay 101 percent of the reasonable costs for the outpatient services less
applicable Part B deductible and coinsurance amounts, plus:
• Show the professional services separately, along with the appropriate HCPCS code
(physician or other practitioner) in one of the following revenue codes - 096X,
097X, or 098X.
The A/B MAC (A) uses the Medicare Physician Fee Schedule (MPFS) amounts to pay
for all the physician/nonphysician practitioner services rendered in a CAH that elected
the optional method. Payment is based on the lesser of the actual charge or the facility-specific MPFS amount less deductible and coinsurance times 1.15; and
• AK - Service rendered in a CAH by a non-participating physician
For a non-participating physician service, a CAH must place modifier AK on the
claim. Payment is based on the lesser of the actual charge or a reduced fee
schedule amount of 95 percent. Payment is calculated as follows:
• [(facility-specific MPFS amount times the non-participating physician
reduction (0.95) minus (deductible and coinsurance] times 1.15.
• GF - Services rendered by a nurse practitioner (NP), clinical nurse specialist
(CNS), or physician assistant (PA)
GF - Services rendered in a CAH by a nurse practitioner (NP), clinical nurse
specialist (CNS), certified registered nurse (CRN) or physician assistant (PA). (The
“GF” modifier is not to be used for CRNA services. If a claim is received and it has
the “GF” modifier for certified registered nurse anesthetist (CRNA) services, the
claim is returned to the provider.) Also, while this national “GF” modifier includes
CRNs, there is no benefit under Medicare law that authorizes payment to CRNs for
their services. Accordingly, if a claim is received and it has the “GF” modifier for
CRN services, no Medicare payment should be made.
Services billed with the “GF” modifier are paid based on the lesser of the actual
charge or a reduced fee schedule amount of 85 percent. Payment is calculated as
follows:
• [(facility-specific MPFS amount times the nonphysician practitioner
services reduction (0.85) minus (deductible and coinsurance)] times 1.15.
• SB - Services rendered in a CAH by a certified nurse-midwife
For dates of service prior to January 1, 2011, certified nurse-midwife services
billed with the “SB” modifier are paid based on the lesser of the actual charge or a
reduced fee schedule amount of 65 percent. Payment is calculated as follows:
For dates of service on or after January 1, 2011, Medicare covers the services of a
certified nurse-midwife. The “SB” modifier is used to bill for the services and
payment is based on the lesser of the actual charge or 100 percent of the MPFS.
MPFS Payment is calculated as follows:
• [(facility-specific MPFS amount) minus (deductible and coinsurance)]
times 1.15.
• AH - Services rendered in a CAH by a clinical psychologist
Payment for the services of a clinical psychologist is based on the lesser of the
actual charge or 100 percent of the MPFS. Payment is calculated as follows:
• [(facility-specific MPFS amount) minus (deductible and coinsurance)]
times 1.15.
• AE - Services rendered in a CAH by a nutrition professional/registered
dietitian.
Services billed with the “AE” modifier are paid based on the lesser of the actual
charge or a reduced fee schedule amount of 85 percent. Payment is calculated as
follows:
• [(facility-specific MPFS amount times the registered dietitian reduction
(0.85) minus (deductible and coinsurance)] times 1.15.
Outpatient services, including ASC type services, rendered in an all-inclusive rate
provider should be billed using the 85X type of bill (TOB). Non-patient laboratory
specimens are billed on TOB 14X.
MPFS rates contained in the HHH abstract file are used for payment of all
physician/professional services rendered in a CAH that has elected the optional method.
If a HCPCS code has a facility rate and a non-facility rate, the facility rate is paid. See
Chapter 23 of Pub. 100-04, section 50.1 for the record layout for the HHH abstract file.
Physician Fee Schedule Payment Policy Indicator File
The information on the Physician Fee Schedule Payment Policy Indicator file is used to
identify endoscopic base codes, payment policy indicators, global surgery indicators,
diagnostic imaging family indicators, or the preoperative, intraoperative and
postoperative percentages that are needed to determine if payment adjustment rules apply
to a specific CPT code and the associated pricing modifier(s). See Chapter 12 of Pub.
100-04 for more information on payment policy indicators and payment adjustment rules.
See Chapter 23 of Pub. 100-04, section 50.6 for the record layout of the Payment Policy
Indicator file.
Health Professional Shortage Area (HPSA) Incentive Payments for Physicians
Section 1833 (m) of the Social Security Act, provides incentive payments for physicians
who furnish services in areas designated as HPSAs under section 332(a)(1)(A) of the
Public Health Service (PHS) Act. This statute recognizes geographic-based, primary
medical care and mental health HPSAs, are areas for receiving a 10 percent bonus
payment. The Health Resources and Services Administration (HRSA), within the
Department of Health & Human Services, is responsible for designating shortage areas.
Physicians, including psychiatrists, who provide covered professional services in a
primary medical care HPSA, are entitled to an incentive payment. In addition,
psychiatrists furnishing services in mental health HPSAs are eligible to receive bonus
payments. The bonus is payable for psychiatric services furnished in either a primary
care HPSA, or a mental health HPSA. Dental HPSAs remain ineligible for the bonus
payment.
Physicians providing services in either rural or urban HPSAs are eligible for a 10 percent
incentive payment. It is not enough for the physician merely to have his/her office or
primary service location in a HPSA, nor must the beneficiary reside in a HPSA, although,
frequently, this will be the case. The key to eligibility is where the service is actually
provided (place of service). For example, a physician providing a service in his/her
office, the patient’s home, or in a hospital, qualifies for the incentive payment as long as
the specific location of the service provision is within an area designed as a HPSA. On
the other hand, a physician may have an office in a HPSA, but go outside the office (and
the designated HPSA area) to provide the service. In this case, the physician would not
be eligible for the incentive payment.
If the CAH electing the Optional Method (Method II) is located within a primary medical
care HPSA, and/or mental health HPSA, the physicians providing (outpatient)
professional services in the CAH are eligible for HPSA physician incentive payments.
Therefore, payments to such a CAH for professional services of physicians in the
outpatient department will be 115 percent times the amount payable under fee schedule
times 110 percent. An approved Optional Method CAH that is located in a HPSA
County should notify you of its HPSA designation in writing. Once you receive the
information, place an indicator on the provider file showing the effective date of the
CAH’s HPSA status. The CMS will furnish quarterly lists of mental health HPSAs to
A/B MACs (A).
The HPSA incentive payment is 10 percent of the amount actually paid, not the approved
amount. Do not include the incentive payment in each claim. Create a utility file so that
you can run your paid claims file for a quarterly log. From this log you will send a
quarterly report to the CAHs for each physician payment, one month following the end of
each quarter. The sum of the “10% of line Reimbursement” column should equal the
payment sent along with the report to the CAH. If any of the claims included on the
report are adjusted, be sure the adjustment also goes to the report. If an adjustment
request is received after the end of the quarter, any related adjustment by the A/B MACs
(A) will be included on next quarter’s report. The CAHs must be sure to keep adequate
records to permit distribution of the HPSA bonus payment when received. If an area is
designated as both a mental health HPSA and a primary medical care HPSA, only one 10
percent bonus payment shall be made for a single service.
